Thiiiinvention relates to burners for fuel or and has for its object to nnie m-ra- *eonipaet dumble and cheap i a hlrrner which will give intense comfsoruse in furnaces used for. melting drisimiiar apparatus. Theinvenmnrlysbeapplied also to household furl'wlll" I i. mes

a Qnwfeah'zre the invention consists of a qbnes ofsuroizl pans of any desir-v able shape or" form, each one forming a Y 1 surface by its bottom'for the upon the oilg'of the pan below of an caused to pass over the oil from S ide bf'th' 'palf to tl'le other, side walls confining the air passage on the sides. An other feature of the invention involves means for main i oil at fixed levels in the pans oil love lating devices individ- 3" ual to each pan, other feature involves the'application of a forced air blast through ducts made in the pans, a plurality of holes from the ducts directing transverse jets of acres the draft of'mixed air' and vapor as it imnes from the pans. Other details of the invention will appear from the foli lowing descri tion in reference to an embodiment of 'e invention as shown in the accompanying drawings, in which Fl 1 is an end view in partial section sofa urner and itsa purtenances, constructed according to my invention.

2 is a transverse section of the taken on the plane of the line 2-2 38 of re 1. In -drawings, I have shown three suoil pans 1, 2 and 3. These pans are preferably made with side walls shown at 4. The pans are made shallower than the lie-aide walls, and the end walls are inclined or The construction is such that the pins can be mounted in so rposed relation to; provide an air p tween the-pans end to end, the passage having, due 4,! to) the inclined ends, first, ,a downward then a horizontal course over the surface-bf oil pans, and, finally, an upit passes out of the pans. of one pen in this way forms a deflector'for' the air draft forcing the air comma the'surface of the oil.

shown at 5, one for each pan. These float controls are of the usual construction, hav- In a float 6, shown in dotted; lines, with a va ve 7 controlling an opening into an oil supply pipeg8,,the flow of oil to and from the 011 control being established through stop cocks 9, and, 10. The floats of the control 5 mechanism; are adjusted at such a height that the oil in each pan will come up nearly to the surface I of the pan. The top an will be usedonly as a reflector and use ,not be supplied with oil. In the forward or discharge 6 and of each pan there is formed a passage 11 to which air under forced draft is supplied by pipes 12 from. a blower 13, valves 14 being used to control the flow. "From the passages 11 small openings 15 permit the air blast to pass out of the passages in a plurality of jets directed across the outflowing mixture of air and oil vapor in line with the burner lip or discharge edge of the pan below, as shown by the arrows, and at this point the mixture is caused to burn with its maximum intensity. By this means, accumulation of carbon on the discharge lip is prevented.

Damper plates 16 adapted to be pushed over the top of the pans from the rear furnish a means for regulating the surface of oil ex osed to the draft, whereby the outut an character of combustion of the urner may be further varied In 0 ration, the apparatus being supplied with 011, a piece of waste or other means, is used to set fire to the oil, combustion will proceed until the pans become heated to the proper degree, when by proper adjustment of the air control valve 14, an intense degree of heat will be produced and with the air supplied first by natural draft as it asses over the oil and next by a subdivi ed forced draft as it commences to burn, will result in complete combustion, no more air being used than is exactly required to produce this result. Instead of air being supplied to the passages 11, steam may be used for this purpose, or a combination of air and steam.

From the above description it will be evident that I have produced an oil burner for furnaces, which ssesses the peculiarity of multi le units, w ich may be aggregated in combinations of 2, 3, 4 or the like, number required by the demands of the farup to any 106 nace. Parts of each unit can, therefore, be standardized without restricting the size of the eventual combination. It will also be seen that each unit performs the four-fold function of an oil container, an oil heater an 'airdsflector or revenberator, and a forced draft nozzle. It will be seen that not only can the oil be preheated to a degree sufiicient to vaporize the same at the desired speed without carbonizing the same, but that the 'air blast also is preheated. It will also be j r' i l,' means for feeding O to each pan from the reservoir, a duct in each panadjgicent to the discharge end, and passages from .each of said ducts in line with burner lip, of the pan below, whereby t e N ciiin an; in said ducts will cool the d sc argeends of the pans and be directed in jets across the burner lips of the pans to prevent the accumulation of carbon thereon.

2. In an oil burner, the combination of a plurality of pans with inclined walls on the 'scharge end, superposed so as to form air passages between them, a reservoir for oil, means for feeding oil to each pan from the reservoir, a duct 1n each pan adjacent to the discharge end, and passages from said ducts in line with the burner lip of the pan below, whereby compressed. air in saiddunts: will cool the discharge ends of the pans and be directed in jets across the burner lips to prevent the accumulation, of carbon thereon. 3. In an oil burner, the combination otf'a plurality ofi pans superposed soas to form air passages between them, each pan having a burner lip on its discharge end, aresemoi'r for oil, means for feeding oil to each :pm from the reservoir, a duct in each an adja cent to the discharge end, passages nomletch of said ducts in line with the burner lip of the pan below, and dampers slidable-ovierithe tops of the pans towardand away from the burner lips for varying the surface of: oil exposed to the draft.
